Anna Ella Carroll (1815 - 1893)

Carroll, who contributed to the Union victory in the Civil War, was
a writer of books, pamphlets, and articles on the state of American politics.
She was also involved in espionage activities for the Union, which attracted
the attention of President Lincoln. He sent her on a mission to the West
to investigate and evaluate the Union's war policy. On that trip, she became
aware of the inadequacy of the Union's military strategy, which led her
to mastermind the Tennessee Plan. It was this plan that finally won the
war. However, her achievement went unrecognized as Lincoln and the War
Department felt it was necessary to"protect" the public from
the knowledge that it was a woman, rather than the army of generals, who
had engineered the victory.
